Aloha planned on Kabuki's visit, and Aloha's personal attempt to thwart Robbit was a ruse. He wanted Robbit to win. Robbit's victory ensured Kabuki's loss of face, with The Pan-Galactic Criminals Club. Without Kabuki's leadership, The Club is vulnerable, with no organization, and nothing to focus its members.
The next step in Aloha's plan is to commandeer The Club, with an air of inspirational leadership. With The Club, Aloha's ultimate victory is much more probable.
The space criminal Aloha perpetually evades the law, even while he takes a brake on his planet. Why?
He pays his space taxes, and his work is profitable. He's given more leeway than most, but he can still be presumptuous. Robbit puts him in line, during these moments, and the space government continues to collect its money.
